1. Copy the whole directory somewhere you like, and create a symbolic link in the PATH for the 'main' file.
   $ ln -s /some/where/you/like/main ~/bin/log

2. Create a config file, save it to ~/.logrc, here is an example:
    # vim: filetype=python:
    #
    # These code is Python code.
    # Only variable assignment will be retained
    
    # Where to store the log data
    dataDir = '/home/joshua/.soogho9E_log_data'
    
    # Author name
    authorName = 'Joshua Chen'
    
    # Author email
    authorEmail = 'iesugrace@gmail.com'

3. Check out the usage.
